W9高速钢铁鳞中合金的成份为8.5—9.5%W,2.7—3.3%Mo,3.8—4.2%Cr,1.2—1.6%V,它是W9高速钢经高温[800—900℃]加热反复锻打从表面脱落而成的,每锻打一吨钢坯直至成材,大约剥落30—40kg铁鳞。一般情况下,铁鳞都是都是作为废品而扔掉,因此,回收铁鳞中的合金元素,不仅可以避免合金的极大浪费,而且还减少元素的污染。 W9 high-speed steel scale alloy composition of 8.5-9.5% W, 2.7-3.3% Mo, 3.8-4.2% Cr, 1.2-1.6% V, which is W9 high-speed steel by high temperature [800-900 ℃] heating repeated forging from Surface off from, and forging a ton of billet until the timber, about 30-40kg iron scales off. Under normal circumstances, the scales are all thrown away as waste, therefore, the recovery of alloying elements in the scale, not only to avoid the great waste of the alloy, but also reduce the elemental pollution.
